Patented July 20, 1937 UNlTED STAT TYPE BED Edd C. Oliver, Adrian, Mich.Application September 10, 1934, Serial No. 743,424 6 claims. (ci. 10iasmThis invention relates to type beds andthe object of the invention is toprovide a type bed having spaced parallel grooves and provided with typeholding bars insertable in the spaced grooves to hold the typetherebetween.

Another object of the invention is to provide a means for holding thetype under pressure at Vthe base so that the type will remain in iixedposition and cannot be readily moved in the normal printing operations.

A further object of the invention is to provide a type bed having spacedgrooves therein into which type holding bars may be inserted to providespaced parallel ribs between which rubber type may be mounted, the typebeing slightly Wider at the base than the distance between the adjacentsides of the type holding bars.

Another object of the invention is to provide a type bed in which sheetmetal type holding bars may be inserted to hold the type, the sheetmetal type holding bars being provided with yieldable flanges in orderto rmly hold the type therebetween.

A further object of the invention is to provide a means for yieldablyholding solid non-compressible type on a type bed in printing position.

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawing in which- Fig. l is a plan view of a type bedembodying my invention.

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the type holding bar which is insertedin the grooves of the type bed.

Fig. 4 is a sectional perspective showing a modied form of type holdingbar for holding the type in position.

Fig. 5 is a similar section showing another modified form of typeholding bar.

Fig. 6 shows the type holding barof Fig. 5 in inverted position.

Fig. 7 is a section showing the simplest form of type holding bar andgroove.

The type bed maybe made of any suitable material, the cheapest formbeing laminated wood, fibre or solid wood as suggested in Fig. 2. Thistype bed l is usually rectangular in form and is provided with spacedparallel grooves 2 shown in Figs. l and 2. The type holding bar is shownmore particularly in Fig. 3 and comprises a metal bar 3 having slopingsides which slope toward the center as shown. These bars may be equal inlength tothe width of the type bedA and are, inserted in the grooves 2as shown in Fig. 2. The grooves 2 are all equally spaced lengthwise ofthe type bed and the type holding bars may 5` intervening groove and thenext size maybe one'r 1.0l

and one-half inches or two inches wide plus the width of the interveninggrooves,` the various type being formed in multiples of the spacebetween the bars plus the width of theintervening grooves. 1 V2in thiscase, the narrowest type 4, shown. in Fig. 2, is held by the type'bars 3positionedin two adjacent grooves, while' the type 5 is held in placebypositioning the next type holding bar in the second groove, as shown,while the type 6 is held by placing the type holding bar 3 in the thirdgroove so that the intervening grooves 2 are spanned by the type asshown at the right of Fig. 2. These type holding bars are provided withsloping or under-cut sides as shown andthe type 25; is slightly widerthan the distance between :the upper edges of the adjacent typeholdingbars so. that it is necessary to press the type into the spacebetween the type holding bars and as the rubber ris under compressionthe type is firmly o held in place. It will also be vnoted that therubber type expands beneath the under-cut edges of the type holding barswhich prevents the type from being pushed over in the inking or printing operations. may be also provided with longitudinal grooves 2a asshown in dotted lines in Fig.v2 which are of the same form as thegrooves 2 but extend longitudinally of the type bed in case it isdesired to reverse the type bed and set the type longitudi nally of thetype bed. In this case, the spacing of the grooves would be the same asshown in full lines in Fig. 2.

case, the portions I il extend upwardly so that bar is shown in Fig. 5inwhich the sheet'rnet'al is formed to providev a C-shapedportion I0having two outwardly and angularlygextending flangesV IVI. The portionVIinay be inserted in the groove 2, as shown in Fig. 5, and the ianges II will engage in the grooves'S onV opposite sides of the@- `type bases.This form, shown in Fig. 5, maybe also reversed or inverted by insertingthe flanges In this rubber'type I2 may beengaged therebetween. The typeholdingv bar shown in Fig. 4 Vmay also be inverted in the'sarne mannerfor holding rubber type andY 'will then haversubstantially the -outersurface `contour of the type` holding bar above. thegroove 2. Forholdinggsolid base type,V

such as wood block or solid metal bases, the sheet.

metalv type bars are positioned with the spring flanges extendingupwardly so that the solid base K type maybe rmlyren-ffaged therebetweenby providing grooves in which the spring flanges engage, while withthecompressible type, .such as rubber base type the type holding bars maybe inverted and need'not be compressible. as the type itself may becompressed into Vthe space `between .the

bars.V

vThe simplest. form of type holding bar and groove is Vshown in Fig. 7in which a `metal bar I5 is kprovided which is rectangular in crosssection and fits .in a rectangular. groove I5" in the type bed l.V .Thistype holding bar win retain the type imposition and may be inserted inthe top of the type bed rather than froin'the edge,'if desired,

I and while it may not hold the'type rasiiirmly as the other forms'oftype holding bars, it `maybe usedwith good results under normalconditions.

AThe sheet metal form of type holdingbar as suggested in'l'igs. 4, 5',and 6 has a flexiblewall permittingthe type to be `introducedtherebetween Vby pressing the side wall of one type bar in a directionaway from the adjacent type holdingl bar permitting an insertion of thetype there-y between. vEither the rubber forrn'or the solidV unyieldableform may be used. Such latter form is preferably Ygrooved to receive theedge of the sheet metal holding bars as more particularly shown in. Fig.5. Rubber type may be used with this character of'type holding barandthey may be shaped of greater width at the base than' between'thecontactingV edgesof the type holding bars. Whenever occurring in theappendedV claims,V the term flexible type holding bars refers to a'forrnof bar such as shown in Figs.

4 to 6 in Ywhich a wall'or ange ofthe type. bar is Y capablejofbeing'fiexed toward its companion wall.

Frornthe foregoingdescription it becomes evident'that the device is verysimple and'efiicient in. operation, will not easily get out of order,provides an easy and simple arrangement for mounting type-on a type bedand provides a device which accomplishes the .objects described.
